SPECIFICATION forming part of Letters Patent No. 759,759, dated May 10,1904.

Application fi1ed April 14, 1903. Renewed April 7, 1904. Serial No.202,078. (No model.)

To (I/ZZ whom it may concern:

Be it known that we, MARSHALL SHEPARD and THEODORE SEDGEWIOK VVIMPENNEY,citizens of the United States, and residents of Edgartown, in the countyof Dukes and State of Massachusetts, have invented a new and lmprovedMooring-Anchor, of which the following is a full, clear, and exactdescription.

This invention relates to improvements in mooring-anchors for vessels,an object being to provide a mooring-anchor of simple construction thatmay be readily set in a waterbed or taken from the water-bed at any timeand that will be practically impossible to draw out by the strain orpull of a vessel attached thereto.

We will describe a mooring-anchor embodying our invention and then pointout the novel features in the appended claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is an elevation of a mooring-air chor embodying our inventionand showing the same in position. Fig. 2 is an elevation illustrating ameans for placing the anchor. Fig. 3 is a longitudinal section of theupper portion of the anchor. Fig. 4 is a top view, and Fig. 5 indicatesa tool that may be employed for placing the anchor.

The anchor comprises a shank 1, designed to be forced into the ground orbed of the water. The lower portion of the shank is screw-threaded, asat 2, so that by turning the anchor it will readily feed into theground. The upper portion of the shank is tubular, thus making thedevice comparatively light to handle, and yet giving it sufficientstrength. At the upper end of the shank is an annular flange or head 8,the interior of which, as here shown, is cup-shaped to receive acorrespondingly-shaped closure 4:, the closure being held in place bymeans of bolts 5, passing through said closure and through the head 3.On the closure 1 is a bail 6, to which the cable 7 is attached, theupper end of said cable being secured to a float 8. As a means forturning the anchor-shank into the ground I employ a tool consisting of aring or collar 9, having 5 lugs 10 on its inner side for engaging inchannels 11, formed in the periphery of the head 3. This ring or collar9 is connected. by means of arms 12 with a tubular rod 13, on which armsor levers 14: are adjustably mounted. The

arms 14 extend from a collar which receives the rod 13, and a boltpassing through said collar may engage in any one of a series ofperforations 15, formed in the rod. By making the arms 1 1 adjustable itis obvious that they may be moved upward to convenient position as theanchor is forced into the ground. In placing the anchor-shank in theground the lugs 10 are to be engaged in the channels 11 and the cable 7carried up and turned once or 5 twice around the arms 14, and thus theinserting-tool and anchor will beheld together while turning the anchorinto the ground. Of course after inserting the shank to the desireddepth the chain is to be released from the in 7 serting-tool andattached to the float.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent A mooring-anchor comprising a shank, tu-

bular at its upper portion and threaded below the tubular portion, a cupshaped annular flange on the upper end of the shank, a closure for saidcup shaped flange, bolts passing through the closure and flange, andmeans on
